From Ziyuan's astonished gaze, Shinji realized that she must have witnessed his fierce battle with the hand demon. In other words, his ‘Susanoo’ had been exposed, and the secret of the kaleidoscope Sharingan was difficult to conceal. Ziyuan was completely unaware of the turmoil in Shinji's heart; she was sizing him up with eyes full of admiration.

“Should I silence her…?” Shinji couldn't bring himself to make that decision.

Suddenly, it seemed that Ziyuan sensed a trace of killing intent from Shinji, and the small bell hanging on her chest erupted with dazzling light.

“What is this…?” Feeling threatened, Shinji took a step back. Others might not know, but he was well aware of the details regarding the priestess of the Demon Country. The small bell on Ziyuan’s chest was a very powerful magical artifact. It appeared to protect Ziyuan, but its true purpose was to seal her priestess powers, preventing the young Ziyuan from recklessly using her abilities to harm those around her. In short, that thing was a binding device disguised as a protective artifact!

To kill Ziyuan, he would have to destroy that bell first, and once the bell was destroyed, he would have to face the unsealed priestess of the Demon Country. Shinji dismissed the thought of silencing her. Ziyuan was indeed a novice priestess, but wasn’t he also a novice ninja? He couldn’t be sure his ‘Susanoo’ could withstand Ziyuan’s sealing techniques, as the priestess of the Demon Country had the ability to seal tailed beasts.

However, doing nothing also seemed unwise. So he thought of a genjutsu, fixing his eyes on Ziyuan and activating his kaleidoscope Sharingan. Through his ocular power, he implanted a psychological suggestion into Ziyuan's mind: “You have never seen me...”

Instantly, Ziyuan's expression became dazed, unconsciously murmuring after Shinji, “Never seen... never seen...”

“Did it work?” Shinji observed her and then secretly breathed a sigh of relief. Fortunately, Ziyuan’s priestess powers were sealed, and she had spent very little time with them; otherwise, with his half-baked kaleidoscope Sharingan genjutsu, it would have been very difficult to implant this psychological suggestion. Even so, he didn’t feel very secure. If he were to meet Ziyuan again in the future, there was still a considerable chance she might recall this memory.

Fortunately, as the priestess of the Demon Country, Ziyuan wouldn’t easily leave the Demon Country, so the probability of them encountering each other in the short term was very low. At that moment, a blaze of fire appeared in the distance, suggesting that a large group of people was rushing toward the palace with torches, anxious and hurried. Clearly, these were the guards of the Demon Country coming to reinforce from elsewhere.

Just as Shinji was troubled about how to return to Konoha, with a ‘whoosh,’ his figure vanished from the spot…

......

......

......

Looking at the familiar room, Shinji realized he had returned. The clock on the wall showed he had been gone for about thirty minutes. This was precisely when he witnessed the hand demon slaughtering the guards and when he killed the hand demon. In other words, he had instantly teleported to the area of the hand demon's invasion, which was the palace of the priestess of the Demon Country, and then instantly teleported back after it ended. It was somewhat similar to the ‘Flying Thunder God Technique.’

“Ah!” A sudden sharp pain hit his eyes. Enduring the intense pain, Shinji quickly closed his kaleidoscope Sharingan, and his crimson eyes quietly returned to their dark color. After a while, the pain in his eyes gradually faded.

Huff... He exhaled a breath of turbid air, his expression somewhat grim. Successfully blocking the invasion and receiving a gift from the ninja world, the amount of chakra within him had indeed nearly doubled; however, chakra is chakra, and the ocular power of the kaleidoscope Sharingan is ocular power.

To put it simply, chakra is refined and synthesized from physical and mental strength and can be restored through rest. It is renewable! The ocular power of the kaleidoscope Sharingan, on the other hand, is a type of high-quality Yin Release chakra. Its total amount is fixed upon awakening the kaleidoscope Sharingan; using more means less remains. Before possessing the ability to convert ordinary chakra into high-quality Yin Release chakra, the consumption of the kaleidoscope Sharingan's ocular power cannot be replenished.

“This time activating Susanoo consumed too much; if I do this a few more times, my kaleidoscope Sharingan will be ruined!” When he activated ‘Susanoo’ in a life-and-death situation before, he hadn’t thought too much. Yet the intense pain in his eyes just now made him acutely aware of the undeniable fact that ‘the kaleidoscope Sharingan is a consumable.’

With a hand on his forehead, Shinji sat down on the bed. The demons invading the ninja world this time were the ones from Demon Slayer, and the probability of them being demons again next time was very high. But he wasn't an expert when it came to dealing with demons! The method he used to eliminate the hand demon was the most simplistic one. After shattering the hand demon for the first time with ‘Susanoo,’ he used the detailed insight from his kaleidoscope Sharingan to confirm that the restored hand demon was smaller than before.

Thus, he confirmed that while demons could continuously recover, they still needed to consume some form of flesh and blood power. As long as he dealt multiple catastrophic blows to a demon in a short time without it receiving flesh and blood replenishment, the demon would lose its ability to recover due to excessive consumption.

However, this method applied to the bulky hand demon, but it might not be effective against other demons. If he were to encounter a demon with high agility and strong tactical abilities next time, it would be very difficult for Shinji to replicate his victory.

“I must find a true way to restrain demons!” Using the Sun Blade to cut their necks was undoubtedly the simplest method, but Shinji wasn’t sure if there were any special ores in the ninja world for forging Sun Blades. He hadn’t seen anything like wisteria in Konoha either. As for sunlight, demons clearly wouldn’t invade the ninja world during the day.

“If demons fear sunlight, then would the ‘Amaterasu,’ known as the Flame of the Sun, be effective against demons?” Shinji suddenly thought of the ‘Amaterasu’ ocular technique of the kaleidoscope Sharingan. The black flames of ‘Amaterasu’ have the property of burning anything without extinguishing. So even if it didn’t have a special restraining effect on demons like the Sun Blade, it could attach itself to the demon and let it turn to ashes in an endless burning.

Unfortunately, Shinji's kaleidoscope Sharingan did not have the ‘Amaterasu’ ocular technique. Just thinking about his kaleidoscope Sharingan techniques made him scratch his head. Both his left and right eyes shared the same ocular technique, named ‘Susanoo Lantern.’ As the name suggests, this is a technique built upon ‘Susanoo’; to activate ‘Susanoo Lantern,’ he must first activate ‘Susanoo.’

Unlike the commonly known ninjutsu-type or genjutsu-type techniques such as ‘Amaterasu’ and ‘Tsukuyomi,’ ‘Susanoo Lantern’ is a relatively rare functional ocular technique. When both ‘Susanoo’ and ‘Susanoo Lantern’ are activated simultaneously, a second pair of eye sockets will appear on the face of Shinji’s ‘Susanoo’ avatar, a pair of empty eye sockets that can accommodate another pair of eyes!

Indeed! The ability of ‘Susanoo Lantern’ is to allow his ‘Susanoo’ to wield a second pair of eyes! From a certain perspective, the birth of this ocular technique might be an amalgamation of the original owner's and his own consciousness as a transmigrator.

In Shinji’s view, this ocular technique is actually very powerful. However, he was troubled by the lack of a second pair of eyes to wield, so his kaleidoscope Sharingan was currently a blank slate, with only ‘Susanoo’ available for use. Compared to the kaleidoscope techniques like ‘Amaterasu’ and ‘Tsukuyomi’ that can be cast with a single eye, ‘Susanoo’ places a much greater burden on the body and consumes far more ocular power.

If he fought every time using ‘Susanoo,’ he wouldn’t be able to last many rounds. Shinji organized his thoughts and contemplated solutions. There were actually solutions. The simplest and most direct approach was to find a pair of closely related kaleidoscope Sharingan to evolve his own kaleidoscope Sharingan into an eternal kaleidoscope Sharingan.

At the very least, he needed to obtain a second pair of kaleidoscope Sharingan that could be wielded by ‘Susanoo Lantern,’ giving him more usable ocular techniques. Following this line of thought, he calculated the several kaleidoscope Sharingan currently in the ninja world: “Excluding mine, there should be four pairs of kaleidoscope Sharingan in the ninja world…”

Obito’s kaleidoscope had one on Obito himself and one on Kakashi. Shizune’s kaleidoscope had one taken by Danzo and one collected by Itachi. Itachi's kaleidoscope was on him. All three pairs of kaleidoscope Sharingan were held by powerful individuals, making it impossible for Shinji to even think about them with his current strength.

The only one he could consider was the deceased Uchiha clan leader, Uchiha Fugaku's kaleidoscope Sharingan. The reason he felt he could consider it was mainly because Fugaku had never revealed the secret of possessing a kaleidoscope Sharingan until his death. Therefore, although the village confiscated Fugaku's Sharingan, they probably still didn't know it was a kaleidoscope.

In this way, the guard level for that pair of eyes wouldn’t be too high. After all, on that night in the mortuary, Shinji had personally seen the medical team removing Sharingan from the bodies of Uchiha clan members and putting them into nutrient tanks. With so many Sharingan harvested at once, the preciousness of Sharingan would inevitably be diminished. Therefore, among the four pairs of kaleidoscope Sharingan in the ninja world, Fugaku's pair had the lowest acquisition difficulty, making it the most likely pair for Shinji to obtain.

“However, I need to first find out where the village has stored the Sharingan...” Although he was eager, Shinji knew he couldn’t rush this matter; he had to plan carefully because if he wasn’t cautious, it was very likely that he would get nothing and lose his own life in the process. Furthermore, quickly improving his physical techniques and ninjutsu was also his immediate priority.

As he thought about this, he gradually felt drowsy, and after the excitement of battle faded, exhaustion washed over him...
